EXHAUST HEAT RECOVERY SYSTEM FOR STEAM TURBINE EQUIPMENT

摘要

PURPOSE: To provide an exhaust heat recovery system which utilizes exhaust heat of a steam turbine condenser to obtain hot water for heating and which is able to cope with variation of a heating load. ;CONSTITUTION: Cooling water drainage from a condenser 4 of a steam turbine 2 is utilized as heat source water, which is fed to an evaporator 5c through a heat source water circulation line 8 arranged between the condenser 4 and the evaporator 5c of a refrigerator 5, and the refrigerator 5 is operated as a heat pump so as to obtain hot water for heating from a condenser 5b. In relation to the heat source water circulation line 8, a bypass line 10 is provided for returning a part of the heat source water from midway of the circulation line 8 via a cooling tower 9 to the condenser 4, and a ratio of feeding quantity of the heat source water to the evaporator 5c to a feeding quantity thereof separated to the bypass line 10 is adjusted in compliance with variation of a heating load.;COPYRIGHT: (C)1993,JPO&Japio
